I am selling a brand new Envision Geothermal Model: NDZ038A10AC by WaterFurnace that was installed in a new custom home, but had light water damage to it due to a leak from the outside pipe. This unit is brand new and never used, though it has been installed and then later replaced. The units when running are very quiet, energy efficient, and utilizes the ozone safe R-410A, and will meet the most stringent EPA requirements for years to come. If you would like to know more about this system, go to http://www.waterfurnace.com/geothermal_heat_pumps.aspx to learn more about it and it's uses. This is a all in one system, and the buyer for this is eligible for the 30% tax credit from our government! As you can see from the pictures, the units are in good condition, and have not been tested since pulled but there is no reason why it should not work like new. If you are in the local area, you are more than willing to check it out for yourself. This item is being sold as is and per the listing that I have given here, good luck and happy ebaying!!!
